T o alla-kom it may concern:

Be it'known that we. Sinox .-Xxmznsox `and LEONARD Haxsox, citizensV of the United States, residing at Russell. in the county of L von, State of Minliesota, liareinvented cer.-

tain new and useful Improvements in Tank- Heaters; vand we do hereby declarefthe following to be a full. clear, and exact description of theV invention, .such as will enable others skilled in the art tol which it appertains to make. and use the same.

. The present invention'is' directed to iniprovemeiitslintankheaters, 'and has for its object to provide a. device of this char ter `which is adapt-edto'rbe'submerged in a t. nk

to heatl the water contained therein for live stock. 'A further object ofthe inventionfis toprovide a tankof this'ch'aracter which is con. structedin such a manner as to furnish a Vmaximum amount of heat with the use of a regulated, so as to insure tion of thel fuel.

. on line 3-3 o small quantity of fuel.

' .A still'further object of the invention'is to provide a tank heater so constructed that .the draft gto the fire box can be conveniently proper consump- -view on line 4'-4 of Fig. 4'Referring to the drawing body of the heater, one end of which terminates in .an upwardly inclined hollow section 2, said section having one corner thereof associated with a plate 3, which provides a duct 4, the purpose of .which Will appear later.

.engage over the pro] A grate -vis provided, and is placed Within the body 1 Withone 'edge resting against the outer Wall of the section 2, said grate being turned upwardly, as at 6, and is provided with hooks'7, which are adapted to 'ections 8 carried by the f'Figr'l. .Figv 4 is a similar lv indicates the -side Walls of the body, said grate having a' cutaway portion 9 to accommodate tlielower 5 end -of the duct 4.

A flue 10 has its lower end communicating -with the interior df the body 1 throughthe 4top thereof, said `flue having its loxver end arranged above the 'pivotally" supportetl damper 11. Slidable. in an opening 12- fornied in the flue 10 isa rod 13, said rod having its inner end connected to a Wire strand 14, which is connected tothe ,damper 11, said rod being alsoA provided with a hea-d 15, .which serves to prevent the rod from dropping into the Hue 10 when the damper lis in its open position. It is obvious that when the rod is pulled outwardly, it will assuine the position asshown in full lines, in Fig. 2, thus holding thl damper in its closed position.

. Extending.transversely through the .body .1 is a. passage 16, which permits Water'to circulate when the heater is in a tank, thus subjectingthe Water to the heat which passes through the upper and lower chambers 17 andlS, which are produced by providing the passage 16.

Since the grate 5 is arranged directly under the lower end of the section 2, it is obvious that fuel can be `fed to the' grate as desired, and it will be further noted that the duct 4 will supply sufficient draft under th u grate to insure proper burning of the fuel. vGf course it Will be obvious that the prod-4 ucts of combustion can pass directly through the iue 10. upon :opening the damper 11, and l when the damper is closed itwill be obvious that the heat will pass through thechambers 18 and 17.

-The body 1 has pair offtransversely disposed angle bars 19,

securedto its bottom ,a f

' which. hold the body spaced from the bottom l of the tank 20, thereby permitting Water to v ,circulate around the body v'1. The upper end ofthe section is closedby a cover-21, and has p ivotally connected thereto a damper 22, which is operable to regulate the draft through the duct 4.

What is-claimed is -v A tank heater comprising ahollon7 body including a `-draft inlet section, a. grate -mounted in thebody, a. draft .outlet pipe communicating' with the interior of' the bodyr adjacent the grate, a circuitous VHue leading dempor and siidable'to'hold the dninpe-r in lo from said grateand communicating with the one or the other ofits positions.
